12 Claims. (Cl. 308-72) a sheet metal side mount pillow bloc-k bearingwhich is formed by stamping out a sheet metal blank of one-piececonstruction, and wherein the blank, after bein stamped, may be suitablybent or folded about and enclosing the bearing to permli't'lthe latterto have universal mounting therein.

.These and other objects oi the invention will be apparent from aperusal of the following specification when taken in connection with theaccompanying drawing, wherein:

Figure 1 is a front viewof the bearing forming:

our invention; l 1

Figure 12 .is a sectional view takenonv the line 2-2 of Figure 1 FigureB is a plan view of the device shown in .Figure 1.;

Figure 4 is a fragmentary view showing the: manner of folding over aportion-of the blank I to. its ultimate form; and

.Figure 5 is .a plan view of the integral blank itself.

vReferring now to the drawings in detail, the

blank from which the pillow block bearing is formed is shown in FigureIt .is formed preferably of relatively heavy gauge sheet metal andcomprises a relatively square hack plate-2 having preferably-at its fourcorners openings it, $3., 18 and ["0 whereby the plate may be fastenedto any side. support. In addition, this plate-like member 2.

is provided with a central opening l2 of rela tively large diameter, andthe marginal edges of this opening "are formed, as shown clearly inFigure 2, with a laterally disposed, circumfer en'tial, short flange M,which flange fi iis provided with a circular wall It about the openingl2, which wall is formed as a part oi a curve to fit about thecurvedwall is of the bearing block 20 .hereinafzterto be described, wherebythis-bean ing block member 2o may have universal adiustmen-t withrespect to the sheet metal .housingrand One side 22 :of the plate-likeback "support -2 :is provided with parallel slits 22s 1 support member.

and 226 which beg-in irom the points 28 and to and extend outwardlythereof to the edge of the side 22 to provide an integral junctiontongue or flange 32 which has an extension 34 projecting well beyond themargin 22 of that side of the plate '2. This tongue 32 is adapted to bebent along the dotted line 35, as shown in Figures 4 and 5, whereby thetongue 3i may be bent forwardly out of the plane of the plate 2, asshown in Figure 4, a distance equal to the length of the portions 323!of the tongue, shown in Figure 5. This tongue is preferably providedwith an opening or hole 38, as shown in Figure 4, and for the purposehereinafter set forth. The outer portion 34 of the tongue 32 is providedwith an integral circular extension to which is provided with arelatively large opening 42 corresponding in diameter to the diameter ofthe opening i2, and this circular or front support portion in is formedby bending the same laterally out of the plane of the tongue 32-34,preferably substantially at right angles thereto as shown in Figure 2.The mouth of the opening i2 is bumped or otherwise formed in conicalcurved formation as at M to provide an inner curved annular portion 45which conforms the circular shoulder 18 on the bearing block 20 so that,as shown in Figure 2, when the bearing block is clamped in positionbetween the annular curved walls It and 44, these walls will bearagainst the opposed spaced apart curved portions l8 and it or" thebearing to permit the bearing to have substantially universal mountingin the sheet metal support and housing. This bearing member so is abearing block, preferably formed to receive a graphite bronze type ofsleeve or a ball bearing type of sleeve of the construction illustratedin Whiteley Patent 2,067,034 of January 5, 1937, or it may be of theconstruction shown in Whiteley Patent 2,123,872 of July 19, 1938, or anyother adaptable form of sleeve. In the instance shown, the bearing block2!! is provided with an annular internal chamber 52 which by means or" apassage'way '5 communicates with the inner wall 58 of the'bearing sleeve50, and in addition the block is provided with an opening '58 in which ashank to makes a tight fit or screwed fit, the shank being a hollowconduit supporting stem for an oil cup 52 having the usual spring heldcover B4. The shank-6'2 of this oil cup passes through the hole .32 ofthe tongue 54, as shown clearly in Figure '2, whereby :the wallsof theopening 38 form means to prevent the bearing 2&3 from moving beyond apredetermined angular position with respect 'to the sheet metal housingmember 32.

addition, the blank portion so of th bearing housing is provided withtwo radially disposed, outwardly extending straps 66 and 68 which areintegral therewith and which straps are preferably elongated andprovided with rounded terminals 10 and (2. Each terminal tab 10 and 12is provided with a fastener opening M and I6 which are preferably of thesame diameter as the openings 4, 6, 8 and ill of the plate 2. These tabs66 and 68 are bent at right angles to the general plane of the flatflange portion 4!], see Figure 2, and each tab 66 and 68 has its outerend bent, as along the lines 16 and 1'8, at right angles to the plane ofthe main portions 80 and 82 of these tabs, as shown at T in Figure 2,with the holes 14 of each laterally bent ear registering with the holes4 and 6 of the plate-like member 2 so that when a fastener is passedthrough the registering holes 14 in the ears l0 and 12, a singlefastener will suflice to clamp the bent down leg portions 66 and 68resiliently against the back plate 2 and the resiliency of the tonguemember 34, together with the curved annular wall portions 44 and IE,will tend to clamp and grip the curved walls l8 and 46 in place whilpermitting their universal movement with respect to the sheet metalhousing member. It will be understood, of course, that additionalfastening bolts will pass through the upper holes 8 and In of the plate2 to hold the same in position.

It will thus be appreciated from the foregoing that we have provided avery simple, economical type of side mount pillow block bearing formedof sheet metal which can be stamped as a unitary blank from a piece ofsheet metal and which then can be bent in a form to desired shape sothat it will surround and enclose and reiliently embrace a sphericalbearing block adapted to hold an elongated bearing sleeve in position sothat a shaft may rotate in the bearing sleeve and be capable ofuniversal mounting in the side mount bearing block wherein the shaft canbe adequately lubricated during its rotation in the bearing sleeve. Itwill also be appreciated that by reason of this construction therequisite resiliency and clamping action is afforded by our simpleone-piece sheet metal bearing. It will also be appreciated that byreason of this construction two of the same bolts or other fasteningmeans may be used for clamping the portions of the one-piece housingabout the spherical bearing and for also forming at least one half ofthe fastening means for attaching the sheet metal housing to the sidesupport.

Obviously the invention is not limited to the specific details ofconstruction disclosed herein but is capable of other modifications andchanges without departing from the spirit and scope of the appendedclaims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent is:
